TL;DR
Alphabet said fast growth in Google AI Mode affected Search monetization because those queries generated less revenue, but it did not quantify the effect. Search revenue still rose 12% in the third quarter, while separate studies and publisher data point to fewer clicks from some AI search experiences.
Google parent Alphabet said on October 28 that rapid growth in AI Mode queries affected Search monetization because those queries were earning less than other searches. Chief business officer Philipp Schindler did not quantify the impact, and Search and other revenue still grew 12% to $63.35 billion in the third quarter. The disclosure matters to publishers and other businesses because AI answers may satisfy users without sending them to the websites that supply information or products.
Schindler made the comment during Alphabet’s earnings call after JPMorgan analyst Doug Anmuth asked why search queries were growing at their fastest pace in five years while Search revenue growth had slowed. Schindler named three factors: foreign-exchange effects, changes in retail and media spending, and lower monetization from fast-growing AI Mode queries. He described exchange rates as the largest driver of the slowdown relative to the second quarter. He gave no revenue figure for AI Mode’s effect and did not say it had reduced Search revenue overall.
The distinction matters: lower monetization means less revenue generated from a type of query, not necessarily a decline in total revenue. Alphabet reported $63.35 billion in Search and other revenue for the quarter, up 12% year over year. The company’s October 29 quarterly filing did not mention AI Mode. It attributed search growth to more queries, advertiser spending and improvements to ad formats and delivery.
Alphabet shares fell 12.6% on October 29, according to Fortune, their steepest one-day decline since the company’s 2004 listing. Reports put the market-value loss between about $475 billion and $500 billion; the available reporting does not support a 15% closing decline. The share move also followed concerns about cash flow and investment spending: CNBC reported free cash flow of negative $9.1 billion and quarterly spending on data centers and chips of $51.4 billion.

The Clicks Behind AI Answers
For publishers, the commercial issue is whether an AI answer reduces the need for a visit. A user who gets a summary in search may not click through to the reporting, discussion or service that informed it. That could affect advertising, subscriptions and referral-based income, though the scale will vary by site, query and business model. The available figures indicate a traffic concern; they do not establish that AI answers caused every measured decline.
Chartbeat data cited by ThorstenMeyerAI.com show Google Search’s share of pageviews across its publisher network falling from about 9% in July 2024 to 5% in July 2026. A Pew Research Center study found users clicked a result in 8% of visits when an AI summary appeared, compared with 15% when it did not. Those measurements cover different periods and methods, and neither provides a direct accounting of the revenue AI features removed from publishers.
Retailers may face a related but distinct change: a customer could research and buy without visiting a retailer’s site. The source reports that Google’s checkout standard covers hundreds of thousands of brands. If transactions increasingly occur within AI-assisted experiences, businesses will need clearer reporting on referrals, sales attribution and the terms governing access to product information.

What Google’s Disclosure Covers
AI Mode is Google’s chat-style search experience. Schindler said queries in the product are three times longer than traditional queries, and Google has reported its query growth is strong. The company’s stated response includes adding more advertising to AI answers. Longer queries and new ad placements could change both how users search and how Google earns money, but the earnings-call comments did not disclose advertising revenue per AI Mode query.
Google previously said its AI features send “billions of clicks to websites every week,” according to the source article. The October earnings call did not provide an updated click figure. That leaves an important gap between Google’s account of traffic across its AI features and the publisher-level measures cited above: they may cover different products, users and definitions of a click.
Rules and commercial arrangements are also developing. The source reports that UK requirements call for an AI opt-out, that the European Union is investigating, and that five French publisher groups filed a complaint on October 29. It also says Google has licensing arrangements with more than 400 publications in a pilot. These developments concern access, compensation and user choice, but they do not resolve the broader question of how AI answers affect traffic across the web.
“The strong growth in AI Mode queries had an impact because of the lower monetization we were seeing in AI Mode.”
— Philipp Schindler, Google’s chief business officer, on Alphabet’s October 28 earnings call
The Missing Revenue and Click Data
Alphabet has not disclosed how much less revenue an AI Mode query generates, how many clicks AI Mode sends to external sites, or how those figures compare with conventional search over the same period. The company’s broad statement about billions of weekly clicks from AI features was not updated on the October call. Revenue impact and referral impact therefore remain unquantified in the material available here.
The publisher figures also have limits. Chartbeat’s network is not every publisher, while the Pew result compares click behavior in sessions with and without an AI summary; it does not by itself prove the summary caused the difference. It is also unclear how much of Alphabet’s share-price fall reflected AI monetization concerns rather than cash-flow results, investment spending or other factors. The reported market-value loss varies by publication and calculation.
More Reporting on Clicks and Ads
The next useful evidence would be comparable, time-series data from Google on AI Mode revenue, ad performance and outbound clicks, alongside clearer reporting from publishers on traffic and earnings. Alphabet’s public statements and future filings may add detail, but no specific disclosure or date for those figures was provided in the source material.
Regulatory and publisher discussions in the UK, European Union and France may also clarify whether sites can opt out, how their material is used, and whether licensing or other compensation applies. Until those details and better measurements are available, the confirmed finding is narrower: AI Mode queries were less monetized, while overall Search revenue continued to grow.
Key Questions
Did Google say AI Mode reduced Search revenue?
No. Google said AI Mode’s fast-growing queries were less monetized and affected the pace of Search growth. Search and other revenue still rose 12% year over year to $63.35 billion.
How much revenue did AI Mode cost Google?
Google did not give a dollar estimate or quantify the revenue difference between AI Mode and traditional searches.
Is there evidence that AI answers affect publisher clicks?
The source cites a Chartbeat network measure of Google’s share of publisher pageviews falling from about 9% to 5% between July 2024 and July 2026, and a Pew study reporting fewer clicks when AI summaries appeared. These findings do not establish that AI features caused all of the change or show the revenue impact for publishers as a whole.
Why did Alphabet shares fall on October 29?
Alphabet’s Class A shares fell 12.6%, their worst one-day decline since the company’s 2004 listing, according to Fortune. Coverage also pointed to concerns about free cash flow and high data-center and chip spending; the available information does not isolate one cause for the market move.
